Title: Improvements in or relating to delay lines
IPC: H01J23/27
Filed: 1955-07-18
Abstract: 780,107. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 18, 1955 [July 16, 1954], No. 20790/55. Class 39(1). In a travelling wave tube the delay line comprises a conductive helix and a conductive comb at least some of the turns of the helix being directly connected to at least some of the teeth of the comb. In one form, Fig. 1, the helix turns 11 are brazed to the comb teeth 12 or the structure could be formed out of a solid block. The helix may be circular, or flattened, Figs. 4, 5 (not shown), or the comb fingers may be curved, Fig. 6 (not shown). In another form, Fig. 7, a capacitive strip 14, near the comb fingers acts as a back plate ; its position can be mechanically adjusted from outside the tube wall. If desired the strip 14 can be coated with loss material or part or the whole of the comb can be coated with loss material from a spray gun. In another form, Fig. 9 (not shown) cooling fluid is circulated in helix 11 and/or within the base of the comb or within the base and/or the fingers of the comb. The comb may, however, cool the helix merely by conduction. Instead of equal numbers of helix turns and comb teeth all connected together, there may be n times as many comb teeth as helix turns or n times as many helix turns as comb teeth. The helix turns may for example be connected in pairs or threes to comb teeth. If there are more teeth than turns, all turns are connected to teeth, but not all teeth are connected to turns. The travelling wave tube, an example of which is discussed with reference to Fig. 10 (not shown) may or may not operate with crossed electric and magnetic fields. The device is designed for wide band operation in the forward fundamental mode. Specification 743,519 is referred to.

Abstract: 479,339. Optical sound recording and reproducing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and WELCH, D. F. July 28, 1936, No. 20907. [Class 40 (ii)] Relates to sound recording or reproducing apparatus in which the record carrier comprises a continuous loop of film x carrying multiple parallel sound tracks, the recorder or reproducer A being automatically dis. placed from one track to another by mechanism under the control of a member E engaging a slot or indentation in the track. According to the invention, the member A is displaced by a rotary member such as K which is driven by a slipping clutch from the main drive F for the record carrier, the member K being normally restrained against rotation by the control member E which bears on the record carrier.

Title: Improved method of painting and baking an article and apparatus for carrying out said method
IPC: B05B16/20
Filed: 1964-05-22
Abstract: 1042215 Coating apparatus P FULFORD 12 May 1965 [22 May 1964] 21162/64 Headings B1R and RU Apparatus for painting an article comprises an enclosed booth 10, a grille platform 13 spaced a short distance above the floor of the booth, means for maintaining a flow of liquid over at least an area of the booth floor beneath the grille, means for introducing clean air into the top of the booth and for extracting air from below the grille during a painting operation, and means for filtering, heating and recirculating the air supplied to the booth during a drying operation. In the arrangement shown liquid is discharged from pipes 18 so as to flow over trays 17 supported beneath the grille 13 to troughs 22 from whence it is drawn and filtered and recirculated. During paint spraying 100% fresh air is drawn into a heater and fan unit and discharged downwards through an air filter in the top of the booth and is extracted from exhaust ducts 16 after passing through a liquid curtain from the trays 17 as indicated by arrows 24, past scrubbing baffles 22a so that it is cleaned and filtered, and is discharged to atmosphere. During drying of the paint the liquid flow from pipes 18 is stopped and the air discharged into the booth is extracted as indicated by arrows 30 through filter 9 to a recirculating duct 7 from whence it is drawn back into the fan and heater unit. During this operation the air intake from atmosphere is reduced to about 10% of the whole, the remainder being extracted from the booth. To prevent leakage of air from the booth through the recirculating duct 7 during the paint spraying period a by-pass duct feeds a small quantity of air from the heater and fan unit to the duct 7 during this period. Safety devices include a limit switch in the fan and heater unit to ensure that there is the necessary air-flow before the heater is switched on and means situated in the exhaust ducts such that should there be an exhaust failure the heater will cut-out. Further an independent electrical thermostat is located in the heater fan casing and the air inlet duct in the roof of the booth may be lightly constructed to provide explosion relief.

Class 61 The supporting elements 2, 6, of the moving and fixed jaws 3, 7, of a wrench are telescopically interconnected by screw and nut adjusting means 4, 13, the adjustment being effected by outer and inner sleeves 8, 11, of which sleeve 8 forms the handle and sleeve 11 forms the nut. These two sleeves, which are interconnected as at 18, 19, form an annular compartment 14 which receives a sleeve like part of the element 6, and within the inner sleeve slides a screwed shank part of the element 2. Thus, by rotation of the sleeve 8 the sleeve 11 turns with it and by its nut part 13 causes the required movement of the moving jaw. A spring 16 bearing against a flange 12 of sleeve 13 and against a removable ring-like abutment 17 on the element 6 tends to urge the jaws apart. In a modification, (Fig. 4, not shown), the fixed jaw is pivoted to lugs on the element 6. Another pivoted jaw arrangement is shown in Fig. 5. which shows two serrated jaws 3b, 7b, carried by supporting elements which have adjustment means as shown in Figs. 1 and 3. The "fixed" jaw is pivoted at 27 to lugs 26 on element 6 and has a pin and slot connection 34, 36, with a spring- urged control lever 31 also pivoted to the element 6. The arrangement is such that the spring returns the "fixed" jaw to the open position when released.
